Common mistakes and solution to them in FC

Now again we face this lovely problem - I got insulted by not tanking the bosses in FC, where we had lvl 98 sin, other sin, me as puller and of course healer and AOE DDs.

Well, cleric stated I should tank more. I told her I am not aps - I will not begin an aggrofight with 2 sins, and I'd rather focus on timing my devour after demon sparks and HF.

" I have never seen sins tank bosses "
Seriously?

Seems FC 80+ and 90+ differ from each other too much nowadays.

Yea... 80+ squads are.... interesting.

I do not mention names here.

Squad: All random people. I was cleric lvl 81, others were barb 81, psy 88, seeker 78, psy 86, sin 86.

The only one experienced in FC was me, though the higher psy seemed to know something as well. Rest had 1-2 FC runs completed before ours, and sin was also doing well thought had a lack of experience.

However, things didnt go well.

At first when I buffed and sin went solo shades, barb suddenly pulled first 3 groups bbefore I was ready with chi. I refused to heal, waited him die and others run back. I explained I cannot set BB without chi, and he went back to town.
Ok, new try, we did small pull to last shade. First boss went very slowly, I was the only one debuffing the boss. I spammed EP, TM and my debuffs as much as I could and kept the barb alive. Some point he forgot tanking, psy got aggro and I managed to keep her alive until barb had aggro back. Boss done.
Magic pull.. awful. Again no waiting for my BB, barb messes, and tried to pull 5 groups at once - barb and psy wiped. Seeker went to clean mobs group per group and I could res the dead. Rest of the pull was ok, though seeker did not vortex at all.

Elementos. They tried to do both sides, I told to focus on 1 and they didnt again debuff elementos at all. Luckily we got boss to tough. Seeker almost refused to wait the 2 mins when glitching. I managed to keep rest wait before attacking.

Then barb tried to pull 1 mob group and bishop group. I had busy time healing and got aggro. Didn't die, charm tick, managed to keep squad alive. Next **** groups went smooth. Sin made the sin pull extremely well and it was his first time - I really do appreciate him.
Bishop boss went down VERY slowly, again only I debuffed. In the end everyone except barb had lost their buffs, and 2 bishies appeared each time. Had hard time healing. No deaths.
Then, rigt after boss dies, barb goes to half pull before even shade was killed. We followed him, managed to do half pull and hoped he wont engage bishops. He didn't but when he noticed not dead shade, he turned back and went to pull to bishop boss room.... squad wipe. All ressed except sin who was alive and went to deal shade. After that half pull was kinda fine, except seeker again refused to vortex.

Lower lvl psychic left, and we got another seeker, experienced one, to run with us. Thank God.
Another half of the pull went smooth as new seeker vortexed. I PMed her and told that squad isnt familiar with FC and we might face more problems. Why I even said that... We INDEED got more problems.
Runewolf. Barb died due to aoe once, he went down really slow, earlier seeker was afk. Boss down, we continue, kill shade and move on next boss. Sleep boss goes smooth until the new seeker goes to pull. The earlier seeker did not AoE mobs she brought - I died when group healing after Messenger's aoe. Sin and seeker die as well. I res with seeker, we come back, I res sin and we continue to last room.
Shade and mobs before last room.. Barb pulls, I'm setting BB, and he does not roar. I die. Again back to town, running, thinking it might turn better.

Last boss. We were fine until 400k was left. Psychic AoEd and replica exploded. I die. Walk back. Die again because lack of barb buff. Walk back. Die because lag and hand following me. Walk back and dead barb realised to res and buff me and experienced seeker tanked it to end. When boss died and his replica ran away, unexperienced seeker ranged it. I died AGAIN, walked back, ressed everyone who died. Buffed, got chi to everyone, told barb to pull.
Yeah, he did pull, allthough he messed with the mobs and first didnt pull all, then went back and took the rest and we were afraid mobs would reset. He pulled to us, didnt roar, luckily seeker was able to tank them as she vortexed.

So yeah.. Havent had this interesting FC in a bit.
b:shocked Let's see what next.

This next story was a bit fail for everyone's part - not really one's fault, it's just... teamwork didn't go right.

We had my cleric, 75 veno (guildie first time in FC), 78 mystic, 85 seeker 80 sin and 82 barb.

Seeker's lvl 102 sin soloed us through to second boss to make it quicker. He asked if he continues with us to 3rd boss to make it smoother, I said IMO 75-85 squad can do it by themselves very well. Ok so he switched to his seeker.

Didn't go well.

Something failed at sin pull - fish died, and someone gathered mobs to the room and started attacking boss. We slightly wiped and restarted the whole thing, barb pulled me through the mobs and rock pulled, all the sudden he didnt pull all mobs, he seemed to want that I'd BB at rock and he would attack boss and mobs and we should kill mob groups, bishies and all at same time - heck no. I refused and said I want a normal rock pull, and IH + chromatic healed boss, no additional mobs. Barb left.

Ok we decided to put seeker tank when we get a DD to cover barb. I focused on finding a DD (was multiclienting and looking for people on my main), seeker attacked boss. I noticed in on cleric, couldnt save squad though as I tried to focus on too many things at same time. Sin lost his nerves and left as well. Seeker brought his sin to kill Drea and then he had to leave.

Result = I had to bring my barb, kicked my cleric out and I soloed the rest for my friend and mystic.
